Called when user drops a column he was dragging.

<div class="definition">
    onColumnDragEnd = function(event)
</div>

This event is triggered when user stops dragging a draggable column. It will receive one argument <span class="property">event</span>
that will contain information what column was dragged.
<div style="height: 10px;"></div>

You can add event listener during the object creation:
<textarea class="javascript">
let grid = new w2grid({
    name    : 'grid',
    columns: [
        { field: 'recid', text: 'ID', size: '50px' },
        { field: 'lname', text: 'Last Name', size: '30%' },
        { field: 'fname', text: 'First Name', size: '30%' },
        { field: 'email', text: 'Email', size: '40%' },
        { field: 'sdate', text: 'End Date', size: '120px' }
    ],
    records: [
        { recid: 1, fname: 'John', lname: 'doe', email: 'vitali@gmail.com', sdate: '1/3/2012' },
        { recid: 2, fname: 'Stuart', lname: 'Motzart', email: 'jdoe@gmail.com', sdate: '2/4/2012' },
        { recid: 3, fname: 'Jin', lname: 'Franson', email: '--', sdate: '4/23/2012' },
        { recid: 4, fname: 'Susan', lname: 'Ottie', email: 'jdoe@gmail.com', sdate: '5/3/2012' },
        { recid: 5, fname: 'Kelly', lname: 'Silver', email: 'jdoe@gmail.com', sdate: '4/3/2012' },
        { recid: 6, fname: 'Francis', lname: 'Gatos', email: 'vitali@gmail.com', sdate: '2/5/2012' }
    ],
    onColumnDragEnd: function(event) {
        console.log(event);
    }
});
</textarea>

or after the object has been created:

<textarea class="javascript">
w2ui.grid.on('columnDragEnd', function(event) {
    console.log(event);
});
</textarea>

Your event listener can be executed before or after the event has been processed. You can also cancel
the default behavior. See <a href="utils/events">Events</a> page in utilities.
